I was skeptical About buying a refurbished model but everything turned out great.The phone is an awesome condition.And it came with a screensaver already on the phone. There was no problems in updating the phone or getting it programmed correctly.

I would say that finding out about back market has been amazing to me. I got an S21G 5G Unlocked from Cellfeee (I chose excellent condition) and it has just been a free gift from cellfeee and back market. The phone was delivered sooner than it was proposed and the phone was really in excellent condition, I have searched to see a scratch on the phone but I haven't seen any. I have been enjoying for about 2 weeks now and there haven't been any issue, infact my phone looks brand new, people don't know that I got it as a refurbished product. I will certainly always by from back market as it just saved me hundreds of dollars and also I would always check out products from cellfeee as they have just proven their reputation to me. I got an amazing product with a token (with respect to quality of product). Thank you back market and also cellfeee for keeping your word. I will keep buying from you.

I have purchased from BackMarket before (back in 2021) and loved my S9+! I recently decided to upgrade to the S21 and, of course, knew that BackMarket would be my best option! This time around I decided to go with the, "Good" condition option (went with "Excellent" for my S9+) and I'm honestly very, very pleased. There are a few scuff marks on the back of the phone, and there's a slight scratch on the screen, though neither are very noticeable! All in all, I would (and do!) - highly- recommend buying refurbished, and buying refurbished from BackMarket at that!

Was delivered in timely manner and physically looks excellent. The characters on the right side of the screen repeat when typing as did my last refurbished phone. Assuming its a defect from an aftermarket display. Its too much of a pain to remove everything and return it. So, I'll just deal with it. Still a great deal.

Benefits of buying a refurbished Samsung Galaxy S21


At Back Market, customers save big compared to the price of new on certified refurbished Samsung Galaxy S21 5G models. The best part is, you don't have to sacrifice performance quality in order to save money; all refurbished devices on our marketplace have been fully reconditioned, cleaned, inspected and tested to the same standards as a new one. This is the biggest difference between buying a used or pre-owned Samsung Galaxy S21 compared to a refurbished one.

Buying a renewed Samsung Galaxy S21 is also a much better option for the environment. A refurbished Samsung Galaxy S21 5G is often a second-hand device that has been restored and updated to meet the Samsung's manufacturer standards, which means you'll be helping to keep old Samsung Galaxy's out of our landfills, reduce electronic waste, and minimize your carbon footprint.


Where to buy a refurbished Samsung Galaxy S21


You'll find the biggest selection, highest product quality and lowest prices on restored Samsung Galaxy S21 5G models at Back Market. That's because we specialize specifically in refurbished tech and take the time to carefully vet every seller on our marketplace to ensure customers are getting reliable devices that perform like-new. We have hundreds of refurbed Samsung Galaxy S21 5G phones in price ranges to fit almost anyone's smartphone budget.

Staying true to our brand, we're also a huge advocate for environmental change. In fact, at the beginning of 2023, we hit a milestone for preventing 1 million tons of carbon emission (CO2e) from entering the atmosphere. You can help contribute to a better circular economy when you shop Samsung Galaxy S21 deals on our platform. 

 

Samsung Galaxy S21 5G warranty and return policy


All Samsung Galaxy S21 5G purchases on Back Market come with free standard shipping, a 1-year warranty, and a 30-day money-back guarantee. We want to make sure you can shop with confidence and find the best Samsung Galaxy for your needs at lower prices.

 

What to expect when buying a refurbished Samsung Galaxy S21 5G


If you're a first time refurbished buyer, you might not be sure what to expect from your purchase. First, understand that your Samsung Galaxy S21 may have external cosmetic flaws depending on the condition you choose (Back Market offers devices of Fair, Good and Excellent quality). However, whatever the condition, any external blemishes will not affect the performance of your Samsung Galaxy and you can expect your device to perform as if it were newly opened directly from the Samsung Store.

You should also be confident that your Samsung Galaxy S21 is backed by a 1-year warranty, meaning in the rare case that any defects arise (outside of accidental damage) within 12 months of your delivery date, then you're entitled to your choice of a repair, replacement or reimbursement. 


Smartphone Trade In


If you already have a smartphone that you're looking to replace, consider trading it into Back Market to give you a little extra budget for your next smartphone upgrade. We make the process simple for you and we'll give you a free online quote when you answer a few easy questions about your current smartphone.
